I’ve gone through a few plate amps (Dayton) trying to power my 15” Paradigm Servo home subwoofer and this thing pushes it very well. I don’t know how they packed all this power in such a small form but it’s great. Review: Saved my Klipsch SW and actually made it better! - I have a Klipsch r-12SW that the amp just died on. Of course it is just out of warranty, so I ordered this hoping to at least get it working until I could upgrade. Little did I know that I had just upgraded. Now, to be fair, I don't know if the improvement I notice is because the included amp was slowly going bad and sound quality was going with it, or if this amp is just better. I tend to think it is the later, since the bass is noticeably tighter and less boomy than the it has ever been with this driver. I think this amp just provides a better, cleaner signal! Excellent product. Highly recommended! ## Features - Upgraded Design: Add Bluetooth to a subwoofer amplifier.

I’ve gone through a few plate amps (Dayton) trying to power my 15” Paradigm Servo home subwoofer and this thing pushes it very well. I don’t know how they packed all this power in such a small form but it’s great. ### ⭐⭐⭐⭐⭐ Saved my Klipsch SW and actually made it better! *by D***E on November 19, 2024* I have a Klipsch r-12SW that the amp just died on. Of course it is just out of warranty, so I ordered this hoping to at least get it working until I could upgrade. Little did I know that I had just upgraded. Now, to be fair, I don't know if the improvement I notice is because the included amp was slowly going bad and sound quality was going with it, or if this amp is just better. I tend to think it is the later, since the bass is noticeably tighter and less boomy than the it has ever been with this driver. I think this amp just provides a better, cleaner signal! Excellent product. Highly recommended! ### ⭐⭐⭐⭐⭐ Use a 32v (5a) AC/DC adapter vs the stock 24v one *by C***R on November 19, 2024* FINALLY - An old school "RMS" power rating. 220w (RMS) at 4-ohms. Here is the kicker, it'll handle 2-Ohm loads with ease and likely over 300w at that impedance (if you run a 32v power brick). That is what I am doing and this amp will deliver. Running the two bottom Yamaha 18" cabs with this subwoofer amp. The main Bluetooth amplifier is a Fosi Audio BT-30D PRO (2.1 amplifier). I run the two top Yamaha cabs with that one. This combo is incredible and pumps out high levels of sound. In order to "really" uncork these digital chip amps -- feed them 32v. I am using two 32v AC/DC adapters on both of the amps with additional cooling (laptop computer cooling tray). This subwoofer amplifier def pushes out the power with a 32v power brick - more than I thought. I am running it with a 4-ohm load on those two Yamaha 18" subs. The amplifier never once has given up or gone into shut down mode. The "GAIN" control is kinda odd and has three click positions. It adds audible line noise, but gives this amplifier more pre-amp gain if needed (for really low SPL subwoofers to match sound levels of the main speakers) UPDATE (Jan, 2025) - Solid buy...this little amplifier is a true subwoofer amplifier with power that will surprise you. Granted, if you're into car audio and 3,000w amplifiers, this is not your thing. For everyone else, this little amp will def please. It sips power -- seriously great to just leave it on (no noise). I got another one! I like these -- can't wait for a 600w version ## Frequently Bought Together - Fosi Audio M01-BT Bluetooth 5.0 300 Watt Subwoofer Amplifier Home Theater Full-Frequency Mini Stereo Audio Hi-Fi Mono Power Amp with Bass Gain Control for Passive Subwoofer Speaker Bass Shaker - Dayton Audio BST-300EX, 300 Watts RMS,Tactile Bass Shaker, 4 Ohms Impedance - Turn Any Surface into a Speaker System - Generates Subwoofer Lows - FosPower Banana Plugs 12 Pairs / 24 pcs, Closed Screw 24K Gold Plated Speaker Plug Connectors for Speaker Wire, Wall Plate, Home Theater, Audio/Video Receiver, Amplifiers and Sound Systems --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sn/products/439695414-m01-bt-bluetooth-5-0-300-watt-subwoofer-amplifier-home](https://www.desertcart.sn/products/439695414-m01-bt-bluetooth-5-0-300-watt-subwoofer-amplifier-home) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-04-26*
